GEORGE W. CHAMBERLAIN, OF KANSAS CITY, MISSOURI.

MEASURING AEPARATUS.

Speccation of Letters Patent.

Patented May 18, 1909.

Application filed August 13, 1998. Serial No. 448,407.

To all whom it may concern:

Be it known thatl l, Grenen W. @Haircare nun, citizen of the UnitedStates, residing at Kansas City, in `the county of Jackson and State oflvlissouri, have invented certain new and useful improvements inMeasuring Apparatus, of which the following is specification.

My invention relates to a measuring apparatus, and my object is toprovide a simple apparatus of this character whereby grain, meal, Hour,beans, peas, or in fact anything that will flow readily through a spoutmay be quickly and accurately measured.

The invention is particularly useful to wholesale groeers, grainmerchants, and others having a large number of sacks to fill with thesame class of merchandise, as the merchandise may be measured asaccurately and much more quickly with my apparatus than it can be with ascale.

Referring now to the accompanying drawu ing which illustrates theinvention, Figures 1 and 2 represent front and side elevationsrespectively of the apparatus. Fig. 3 is a broken vertical section on.line lll 111 of Fin'. 2. Fig. 4 is a horizontal section on line VIVe-IVof Fig. 1.

l designates a hopper or other suitable receptacle containing materialto be measured.

2 designates a spout which may consist of one or more sections. ln thedrawing, l have shown it consisting of a stationary section 3,communicating with hopper 1, and an adjustable section 4 telescopicallyengaging section 3, so that the apparatus may be usted to measuredierent quantities of the material. The lower terminal of section 3 issplit at 5 and provided with lugs 6 and a bolt 7, so that it may bedrawn snugly around section 4, and thus prevent leakage of materialbetween the sections. Section 4 is provided with a scale 8, so that itmay be readily set to measure any desired quant-ity of material.

9 designates a housing` formed integral with section 3, for thereception of a slidevalve 10, whereby the flow of material throughsection 3 is controlled. Valve 10 is provided with a port 11, which maybe brought into coincidence with section 3 by sliding the valve to theright, as indicated by the dotted lines, Fig. 3.

Section 4 is provided with a housing 12,

`for the reception of a slide-valve 13, whereby theflow of materialthrough section 4 is controlled, said valve being provided with a port14, which may be brought into coincidence with the opening throughsection 4 by sliding the valve to the left, as shown by full lines, Fig.3.

15 designates a vertical shaft mounted in bearings 16 and 17, extendingforwardly from housings 9 and 12 respectively. Said shaft is providedwith crank-arms 19 and 20, connected respectively to valves and 13 bytwo links 21 and 22, forming toggles for actuating the valves. Shaft maybe actuated either`by power or through the instrumentality of a handlever 23 fixed to the lower portion thereof by a set-screw 24. Crank-armis also fixed to the lower portion of shaft 15 by a set screw 25, whilecrankarm 19 loosely engages said shaft, so the same may slidelongitudinally therethrough when section 4 is adjusted upwardly ordownwardly. Crank-arm 19 is prevented from moving up or down with shaft15 by an integral hub 26, extending through bearing 16, and provided atits lower end with a collar 27 secured thereto by a pin 28. Hub 26 isprovided with a feather 29 which enters a longitudinal groove 30 inshaft 15, so the latter may slide through the hub and be turned thereby.lWith this arrangement, it is obvious that when lever 23 is thrown tothe left it will through the instrumentality of shaft 15, crank-arms 19and 2O and links 21 and 22, slide the valves to the left and therebyclose section 3 and open section 4, so that the material which ismeasured by the space between the valves may be dis- 'charged fromsection 4.

Section 4 is adjusted upward or downward to diminish or increase eachcharge of material by two vertically arranged screws 31 and 32, theformer of which is journaled at its lower end in a bearing 33,projecting rearwardly from housing 12, while its upper portion isthreaded in a bearing 34, extending rearwardly from housing 9. Screw 32is journaled at itslower end in a bearing 35 projecting forwardly fromhousing 12, and is threaded in a bearing 36 extending forwardly fromhousing 9. The screws are simultaneously adjusted by bevel gear wheels37 fixed to their lower portions, bevel gear wheels 38 intermeshing withbevel gear wheels 37 and fixed to a horizontal shaft 39, a ratchet wheel40 fixed to the lower terminal of screw 31, and a hand lever 41, looselymounted on the lower portion of screw 31 and provided with a doubleacting pawl 42', either end of which isl adapted to engage the ratchetwheel 40, so that screws 3l and 3Q may be rotated in either direction.

43 designates a bushing remcnably secured in section 4 by a set screw"4:5, so that the oa paci'ty' of section 4 may be reduced to a n-nnimum.i Y 46. A'desip'natesV a downwardly tapering hood `for directingthedischarging' material into sacks when desired said hood is removablyconnected with the lower terminal of sectiony by" two oppositelydisposed bayonet joints 47. f

p From the abovey description it is obvious that I have produced ameasuring apparatus, which is siniple in construction,- accurate inmeasuring material and easypto manipulate.

Having thus described my invention, what i claim and faire w am@ byteam- Paent isf n apparatus of the character described, consisting` of aspout having two sections, o ne of w ich is telescopioally connected tothe other, means for adjusting said telescopic section in or out, avalvel cooperating with eachsection of the spout, for measuring andcontrolling the flow of material oEoRoE w.
